I-Acrylonitrile: Yeyiphi imizi-mveliso esetyenziswa kakhulu? Lithini ikamva le-acrylonitrile?

I-Acrylonitrile iveliswa yi-oxidation reaction kunye nenkqubo yokusulungekiswa kusetyenziswa ipropylene kunye namanzi e-ammonia njengemathiriyeli ekrwada..Ngaba luhlobo lwe-organic compounds, ifomula yemichiza ye-C3H3N, lulwelo olungenambala oluvuthayo, oluvuthayo, umphunga kunye nomoya unokwenza umxube oqhumayo, kwimeko yomlilo ovulekileyo, ubushushu obuphezulu kulula ukubangela ukutsha, kunye nokukhulula igesi enetyhefu, kwaye i-oxidant, i-asidi eyomeleleyo, isiseko esomeleleyo, i-amine, i-bromine reaction ngobundlobongela.

Isetyenziswa kakhulu njengento ekrwada yefiber ye-acrylic kunye ne-ABS/SAN resin. Ngaphandle koko, isetyenziswa ngokubanzi kwimveliso ye-acrylamide, i-pastes kunye ne-adiponitrile, irabha yokwenziwa, iLatex, njl.

Aizicelo

I-Acrylonitrile zizinto ezintathu ezinkulu zokwenziwa (iiplastiki, irabha yokwenziwa, ifayibha yokwenziwa) imathiriyeli ebalulekileyo ekrwada, ilizwe lethu i-acrylonitrile yokusetyenziswa ezantsi komlambo igxininiswe kwi-ABS, i-acrylic kunye ne-acrylamide amasimi amathathu, ii-akhawunti ezintathu malunga ne-80% yokusetyenziswa iyonke ye-acrylonitrile. Kwiminyaka yakutshanje, ngophuhliso lwezixhobo zasekhaya kunye neemoto, i-China iye yaba lelinye lamazwe akhula ngokukhawuleza kwimakethi ye-acrylonitrile yehlabathi. Iimveliso ezisezantsi zisetyenziswa kakhulu kwizixhobo zendlu, iimpahla, iimoto, amayeza kunye nezinye iinkalo kuqoqosho lwelizwe.

I-Acrylonitrile iveliswa yi-oxidation reaction kunye nenkqubo yokucoca ipropylene kunye ne-ammonia. Isetyenziswa ngokubanzi kwimveliso ye-resin kunye ne-acrylic fiber. Ifayibha yeCarbon yintsimi yesicelo enemfuno yokukhula ngokukhawuleza kwixesha elizayo.

Ifayibha yeCarbon, njengenye yezinto ezibalulekileyo ezisetyenziswa ezantsi kwe-acrylonitrile, yinto entsha egxile kuphando nophuhliso eTshayina. Ifayibha yekhabhoni iye yaba yinxalenye ebalulekileyo yemathiriyeli ekhaphukhaphu, kwaye ngokuthe ngcembe ukusuka kwizinto ezidlulileyo zetsimbi, kwimimandla yasemkhosini neyezomkhosi iye yaba yeyona nto iphambili yesicelo.

Ngophuhliso oluqhubekayo lwesayensi kunye netekhnoloji, imakethi ye-acrylonitrile ibonisa indlela enkulu yophuhliso:

1. ipropane njengento eluhlaza yomgca wokuvelisa i-acrylonitrile ikhuthazwa ngokuthe ngcembe;
2. uphando lwee-catalysts ezintsha lusengumxholo wophando lwabaphengululi basekhaya nakwamanye amazwe;
3. isixhobo esikhulu;
4. ukugcinwa kwamandla kunye nokunciphisa ukukhutshwa, ukulungiswa kwenkqubo kubaluleke kakhulu;
5. ukucocwa kwamanzi amdaka kuye kwaba ngumxholo obalulekileyo wophando.
